Horizontal Injection Molding Machines are also called injection molding machines or injection molding machines, which include vertical, horizontal, and vertical-horizontal compound types. So what should we do if our high-quality injection molding machine fails semi-automatically?
The semi-automatic operation of high-quality injection molding machine is by opening the safety door, closing the stroke switch, and sending a signal to start the semi-automatic action of the machine, and then closing the mold. After encountering the SQ4 stroke switch, the mold closing ends and the injection starts at the same time. The injection time relay starts timing and the injection time When the time is up, the pre-molding starts, and when it touches the limit switch that has finished pre-molding, it starts anti-flow. When it touches the anti-flow limit switch, the cooling time relay starts timing.
When the time is up, the mold opens, and then the mold is opened. After the mold-opening termination travel switch, perform the ejection action. After the ejection termination travel switch is encountered, perform the ejection-retraction action. After the ejection termination travel is encountered, wait for the safety door to be opened. In this way, the work is repeated. It can be seen from the above that if the manual operation is normal, it is usually caused by the trip switch and time relay not sending a signal. According to the failure of the semi-automatic action in the mechanical cycle, compare the electrical appliances and hydraulic schematic diagrams to find out the corresponding control components, and check to solve them.
